My good news is that yesterday I had the all clear on my thyroid hormone levels - many years ago my thyroid became overactive (which is a serious condition) which was sucessfully treated, but in the process (as the doctors err on the side of caution to avoid the need to repeat the process) I became underactive - this is far less serious and can be readily treated by taking thyroxine (which I suspect some of you alredy do) to get the correct level of thyroid hormone. I was on a steady level for many years, but in November due to stress my thyroid suddenly became further underactive (partially accounting for why I was in hospital for over 2 months from December to early February. Once the doctors realised this they boosted my medication and I recovered. But once out, my own doctor took another blood test late February, found that I was getting too much so lowered it. And I am now in the clear
The thyroid is very important in controlling the metabolism. If the thyroid is overactive (which is serious), the results can be increased blood pressure, increased pulse, feeling too hot, trembling (the shaking in the hands is noticeable), loss of weight, osteoporosis, and can lead to mood swings resulting in psychotic episodes.
If the thyroid is underactive which is less serious, the results typically are feeling cold, feeling very lethargic, gaining weight, and becoming depressed.
Although overactive is less common, underactive is very common particularly in women in their 50s (that's my observation anyway).
I know this is not a medical thread but I have gone into some detail of the symptoms as there is every possibility that someone reading this may recognise the symptoms in themselves. My advice obviously is if you think this may be the case see your doctor, tell them your symptoms and suggest that a blood test for your thyroid levels might be sensible.
